Operation
Connecting thermocouples
1. This meter accepts any K-type thermocouple with spade plugs (sub-miniature type with one
spade wider than the other).
2. Plug the thermocouple into the meter's thermocouple input jack.
Measuring
1. Press the
button to turn power on. The meter will perform a short self-test.
2. Press the °C/°F button to select the desired temperature unit of measure. A display icon will
reflect the selection.
3. If a probe is not connected to the meter, the “--------” indication will appear on the display.
4. Contact the object to be measured with the probe.
5. Read the measured temperature in the display.
Note: If the display indicates “OL” the temperature is outside the measurement range.
Maximum, Minimum and Average Function
1. Press the MX/MN button to capture the Maximum (MX), Minimum (MN) and Average (AVG)
temperature values.
2. The lower secondary display will appear with MX and the maximum recorded temperature
displayed. The upper display will continue to measure the current temperature. The lower
display will update only when a new higher temperature is measured.
3. Press the MX/MN button to step through MX, MN and AVG.
4. The AVG value is the true average of the measured values. Averaging will occur for 4 hours,
then the average will reset and begin a new 4 hour cycle.
5. To exit the MX/MN function, Press and Hold the MX/MN button until the display returns to
standard operation.
Note: The Auto Power Off feature is disabled when the MX/MN feature is selected.
